METHOD FOR FASTENING ARTICLES TOGETHER.

Application inea may 14. 1925. serial No. 30,385.

This invention relates to an improvement in a method for fastening articles together,

and more particularly in a method for fas# this is that the rivet is of a different composition, and consequently while the lrivet head may be finished down on the surface of the outer face, it acts differently when exposed to the weather, and consequently within a short time has a different color from the surrounding face. f

Another means previously. provided for this purpose has been to cast the outer plates with lugs on the rear face, which lugs were milled and drilled to form hollow integral rivets. The inner plate is provided with a plurality of holes spaced in the same relation as the rivets, so that the plates can be joined by inserting the rivets through the holes and ending them over in the usual manner. The objection to this feature, however, is that the rivets bein east of the .same material as the outer p ate are too brittle and have a tendency to snap off.

The primary object of this invention is to avoid the objections pointed out above, and to provide a means by which Ithe metal pieces are rigidly united by concealed fastening means, which means are of material much more malleable than the united metal pieces.

A further object of this invention is to rovide fastening means which can be easily applied andV rigidly secured to one plate, and which can be replaced by others if in any way the first prove unsatisfactory.

Other objects of this invention will appear from a consideration of the following description taken in connection with the drawings which form a part thereof, and in which- Fig. 1 is an lelevation andFig. 2 is a sectional view, along the line`2-2 of Fig. 1, illustrating the first step in carrying out this process; i

Fig. 3 isean elevation, and Fig. 4 a sectional view, along the line 4-4 of Fig. 3, illustrating the second step of the process;`

Fig. 5 is.an elevation and Fig. 6 aseotional view, alon the line 6 6 of Fig. 5,

illustrating the t ird step of the process;

Fig. 7 is an elevation and Fig. 8 a sectional view along the line 8-8 of Fig. 7, i1- lustrating the fourth and lasthstep 1n this process; v

Fig. 9 is a plan view showing the back I of a card holder; and

Fig. 10 is a sectional view, illustrating the card holder secured to a metal plate by means of this invention.

Referring tothe drawings, Figures 1 to 8 inclusive illustrate for example the use of this invention in mounting a face plate or strip 10 to a backing plate 11. In the rear face of the plate is milled an annular recess 12 having a central post 13, this recess being preferably of a depth equal to about half the thickness ofthe plate 10. In the recess 12 is placed a hollow rivet 14, the central hole 15 of which is substantially the diameter of the post 13. The base ange 16 of the rivet 14 bears against the outer wall of' the recess and preferably the contact of the flange with the outer wall of the recess and the contact of the post 13 with the center of the rivet insures the proper location of the rivet in the recess.

After the rivet has been so located, the edges 17 of the recesses are forced down over the flange 16, as shown in Figure 6, thus securing the rivet in position. Through the backing plate 11 isfdrilled a hole 18, through which the rivet 14 projects when the parts are assembled, as shown in Figure 8. The projecting end 19 of the ri-vet 14 is now upset to secure the plates 10 and 11 together.

Referringto Figures 9 and 10, the reference numeral 20 is employed to designate a card holder which is to be secured to the front face 21 of a metal drawer. The method formerly followed has been to make the card holder 2O of cast bronze and to cast integral with the holder the rivets by which the holder is seeuredin position. In the usual practice these card holders are secured in place by the use of four fastening means, one at each corner, as indicated by the numbers 22, 23, 24 and 25. By following this invention the card holders will be secured to the face of the drawer by means of hollow rivets 26 secured in the holder,'as described above, ahd upset behind the front face 21.

While two embodiments of .thisl inventionv have been shown and described, applicant is not limited thereto, since it is obvious thatA other embodiments can be made without 'de' I claim ,as new and for whichI desire protection -by Letters Patent is:

- The method of 'riveting jtwgmlfplates to ether consistingin first, orniingan annu r recess in the rear face "ofthe front. plate around a central postg-glsecond, placing a hollow 'rivet Iianged at one end over said post 'with the flange resting in said recess;

third,-forcing the outer edges ofv said ,recess4 down. over said flange; ourth, forming a jhole. inthe other-of said .plates fifth, as-

sembling 'said plates with said rivet through said hole and projecting beyond said second named plate;l and sixth, upset" said projecting end of'said rivet to f asten said lIl igftestimony whereof. I have aliixed my signature. f f Y Y Y DWARD H. ELLIsoN.
